Inspection Arrows are color coded to identify problem areas on a circuit board or any other equipment. Inspection Arrows point directly to the areas requiring action on PC Boards. You can use them on any clean or dry surface. Color coded inspection arrows are available in Vinyl material. They are packaged as 1000 arrows per roll in a 3" core.
